Well im a gamer and i thought i'd might to test this new version of linuxmint 13.. -But boy was i dissapointed -first i noticed it's mice driver was way to slow and laggy .. My scrollwheel don't react as it use to be.. Like lagging?.. and after a while it works and then same lag again?..

Never had that problem on any other version of any linux distrobution before?

I'm very frustrated here now?.. -how can i fix this.. last linx dist i used was the older ubuntu 11.04.. which worked fine with almost everything.. But i tried 12.04 and had problems . -what i do to fix this mice drivers or .. what ever it is?

So how does the mouse react otherwise? If you simply move the pointer, is it ok? If you click on an app, does it open in reasonable time?

The K70 seems to be an ok unit, with a dual core 6600? Is that the one or is it the AMD processor? How much RAM does it have?

Does it happen all the time, or in one app, or when many apps are open (for example, if you have LibreOffice Word open, and Firefox, does it happen more in one than the other)?

As remoulder said, and as sunwukung did, it's probably better to post as much useful information as you have so that we have something to work with. Even the desktop would help, as there are various ways of getting to the same end on different desktops, so is it KDE, Gnome, Cinnamon, XFCE or something else?

Did the problem start as soon as it was installed, or can you remember installing something recently?

If you can go to start - administration - system information, then go to devices - input devices, what does it show?

When does the lag happen?- Always (upon startup)- Only in one app (Firefox, something else)- When multiple apps are open

Have you lowered the resolution - does it still continue?

Can you start Linux as a live session - does it happen then or did it only happen after installation?

Do you remember changing/adding any apps?

What is your desktop? Gnome - KDE - Cinnamon - xfce - something else?

Have you run updates?

Just so you know, I'm on Nadia with either Cinnamon or KDE running on a dual core E8400, 4Gb RAM, 320GB HDD, xorg 1.13.0 on 1366x768, intel graphics chipset, installed about 16Gb of further apps from the repo and it's never missed a beat. I did have a mouse at one stage that ran on PS/2 that......

When does the lag happen?hmmm - this one is tricky. I'm a web developer, so I don't generally need a powerful deck, or run many native apps. Generally speaking, I've got a couple of tabs open in Chrome, and Sublime Text. I figured it might be the browser, i.e. loads of Javascript processes, or Flash - but right now I've got the lag and I've only got the forum open. In addition, I've noticed it when I have no browsers open.

Have you lowered the resolution - does it still continue?I haven't lowered the resolution - although I was considering switching the USB reciever port.

Can you start Linux as a live session - does it happen then or did it only happen after installation?I haven't tried yet, I'll give it a whirl this weekend.

Not too bad. A T4400 must be around 4-5 years old? It's a base dual core, but still should do the trick.

Have you tried disabling addons? If you're in Chrome, it's under tools - extensions, click the trashcan icon. I can't remember but I think there was a way to start Chrome with addons disabled. I think from the command line it's something like --disable-extensions - can anyone help with this?

Just as a test, to see if it's heavy on the graphics resolution.

LAMP server may have something to do with background running processes. I had a LAMP server on the Elastix box, which is only a single core 3GHz processor and it didn't lag, but I am running xfce on it (a lightweight desktop)

If you're at the login page, there will be an icon that allows you to change the session. Usually "Last session" is the default, but you would be able to see a list of one or more desktops, that's how you will know. If you can also go Menu - Administration - System Information and click Operating System, it should list your desktop environment.

If you are using Gnome, you can, at login by clicking the session icon, possibly also see the ability to log into more than one Gnome session (the other being a "safe mode"). You can also test with this.

Have you run updates?Yup, several - I've installed restricted extras too.

That's a good thing. Sometimes updates will fix bugs that would also fix your issue. It seems that it hasn't yet.

I'll give a wired mouse a go this weekend

If it's mostly Chrome that's lagging, you could also install Firefox and see if you get the same result with a different browser. By elimination, you can 90% of the time figure out what's causing the issue, then have the ability to concentrate on that.

Do sites with images take a long time to load (or are they loaded before or after the lag issue happens). That is, if you wait for a while for all image to load, would it then still lag?

How are videos on Youtube - are they streaming well?

Can you post what is in your /etc/hosts file? Here is mine (I am on an elaborate network configuration on 255.255.0.0, so I'm running a few virtual networks with different subnets). Things in <> are specific to this computer.

Video streams fine from youtube, I can't really pin the lag on any specific thing when watching the system monitor - although the processor seems to get a little too busy (60-100%) on web page requests, which seems odd? Then again, I've seen the mouse lag when it's on 60% so I'm not sure it's that. I've tried FF and Chromium, both in "incognito" mode to disable any plugins - but the lag still occurs.

Just dropped the resolution, seems to be happier - although I'm not - I've run the same deck on dual boot with W7 / Ubuntu 10.04 for the last 2 years and had no issues at the higher resolution (or with the same mouse) - I regularly used W7 to do Photoshop work back when I was freelancing. I have had issues with nvidia drivers on later versions of Ubuntu, but don't know if these are required for Linux Mint to resolve the problems.
